    • OR - At least one of the terms joined by "OR" must appear in the pages or documents.
    • NOT - The term or terms following "NOT" must not appear in the pages or documents. Some search engines substitute – for NOT.
    • FOLLOWED BY - One of the terms must be directly followed by the other.
    • NEAR - One of the terms must be within a specified number of words of the other.

      • E.g.: Hotmail, Yahoo!Mail, Gmail, etc.
    • Email client—program housed on one computer and accessible only at that computer.
      • E.g. Microsoft Outlook, Mozilla Thunderbird (free)
    • You can use a local email client to manage your web-based email accounts, if you have more than one. (For advanced emailers)
    • An email address is much like your mailing address—don’t give it out to just anyone.
    • What is Spam? It is mass distributed, unsolicited junk email. Some is malicious, so never open these messages.
    • How to know if it is spam? Did you give this person your email address?
    •   Choose a provider:
      • Gmail by Google
      • Yahoo! Mail
      • Hotmail
      • Or use your Internet Service Provider (Comcast, BellSouth, etc.)
    • Follow their process for signing up
    • Start emailing!
    • To line—email receiving message
    • Subject line—summary of topic
    • CC line—carbon copy; recipient should see information but is not the main target
    • BCC—blind carbon copy; recipients see only what is in the To line; used for privacy when bulk emailing
    • Body—contains message
    • Attachments (optional)—additional files you wish to send that cannot fit in the body.
    • Always use the Subject line—Summary of message
    • Visual appearance=tone: Do not type in all CAPS
    • Email is as good as a written letter—use capitalization and punctuation where appropriate.
    • Don’t forget to sign your name
    • If sending to many people, it is always appropriate to use the BCC function—some of your friends may not want their address distributed.
    • Don’t aimlessly forward messages that you think are cute or funny—consider the recipient before forwarding
    • Time for questions and demonstrations.
